STANCHION.

SPECIFICATION formingpart of Letters Patent N 0. 722,271, dated March 10, 1903.

Application filed July 14, 1902.

To all 1071,0127, it may concern.-

Be it known that I, LoUIs H. ANDERSSON, a citizen of the United States, residing at Wardner, in the county of Shoshone and State of Idaho, have invented certain new and useful Improvements in Stanchions; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in cattle-stanchions.

The object of the invention is to provide improved quick-acting operating means which will enable a number of stanchions to be operated simultaneously or one or more operated without requiring the operator to pass between the animals.

With the above and other objects in view, which will readily appear as the nature of the invention is better understood, said invention consists in certain novel features of construction and combination and arrangement of parts,which will be hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a plan view of a series of stanchions embodying my invention. Fig. 2 is a side elevation thereof, partly in section. Fig. 3 is a detail horizontal section on line 3 3 of Fig. 2.

Referring now more particularly to the drawings, 1 represents astanchion-frame having upper and lower parallel longitudinal bars 2 and 3 and vertical truncated triangular boards 4, forming stanchion-openings, in each of which are arranged a rigid vertical stanchion-bar 5 and a movable stanchion-bar 6, the latter being pivoted at its lower end, as shown at 7, between the bars 2 and having its upper end movable in and projecting upward through spaces between the bars 3.

8 denotes a longitudinally-sliding operating-bar mounted upon one of the bars 3 and provided at one end with a pivot-pin 9. This pin fits within a segmental groove 10 in the point of a cam-lever 11 and is confined therein by a strap or shoe 12, secured to the camhead 13 of the lever. The head 13 works within a yoke 14, fixed to one of the end up rights of the frame 1, and is confined therein by a pin 15. When the lever is depressed,

Serial No. 115,492. (No model.)

the shod convex face of the cam-head rides on the body of the yoke and the pin 9 is pushed upon to slide the bar 8 in one direction. When the lever is elevated, the strap draws upon the pin and slides the bar in the reverse direction. The downward movement of the lever swings the stanchion-bars 6 closed to confine the animals, and to lock the parts in this position a bail-fastener 16 is provided, which is adapted to he slipped over the free end of the lever to hold the sliding bar and pivoted stanchion-bars from movement.

The bar 8 is provided with connections for operating each stanchion-bar 6, the same comprising a fixed clasp 17, bearing against one edge of the bar 6 and having alateral arm 18 to bear upon the opposite side of the bar 6 from the bar 8, said catch serving to hold the bar 8 from outward displacement and at the same time to force the bar 6 closed when the bar 8 is slid to the unlocking position by the upward movement of lever 11. A latch-lever 19 is mounted to swing vertically in bar 8 and has a lateral arm 20, hearing on the opposite edge of the bar 6 from the arm 18, so that when the bar 8 is moved inthe reverse direction by the downward movement of the lever 11 the arm 20 will swing the bar-6 toward the bar 5.

In operation, as all the bars 6 are connected in a similar manner to bar 8, the upward movement of the lever 11 will move the bars 6 away from the bars 5 and the downward movement of the lever will force all the bars 6 toward the bars 5. If it be desired to prevent either bar 6 from being operated by the movement of the slide 8, the cooperating latch 19 is swung up, allowing the bar 6 to swing against the adjacent board 4, so that it will not be moved when slide 8 is reciprocated.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the construction, mode of operation, and advantages of my improved stanchion will be readily apparent without requiring a more extendedexplanation.

It will be seen that the device is simple of construction, efficient in use, and susceptible of application to existing stalls.

' Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a stanchion, the combination of movable stanchion-bars, a slide to which they are connected, a fixed yoke and a lever having one end curved to form a cam, slidable and fulcrumed in the yoke and connected to the slide, to operate the latter, substantially as described.

2. In a stanchion, the combination of movable stanchion-bars, a slide to which they are connected, a fixed yoke, a lever having one end curved to form a cam, slidable and fulcrumed in the yoke, and connected to the slide, to operate the latter, and means to engage and lock the lever in position to hold the stanchion-bars closed, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
